Nintendo is still the least environmentally-friendly of the big three videogame companies, according to the latest Greenpeace grading.

Nintendo has once again come under fire for the use of certain materials in its games consoles, although this year does slightly better for disclosing carbon footprint and energy efficient chargers for the DSi. Here's what Greenpeace said (via Kotaku):

"Nintendo scores most points on chemicals; it has put games consoles on the market that have PVC-free internal wiring. It has banned phthalates and is monitoring use of antimony and beryllium. Although it is endeavouring to eliminate the use of PVC, it has not set a timeline for its phase-out.

"It continues to score zero on all e-waste criteria.

"It scores points on energy criteria, for the energy efficiency of its low power AC adaptor for the Nintendo DSi, which meets the requirements for external power supplies in the Energy Star programme. It also retains a point on energy for disclosing carbon dioxide (CO2) emissions from its own operations."

That's a improvement over last year, when Greenpeace condemned Nintendo for having "an incredibly poor standard of communication regarding this issue."

Nintendo is bottom of the three on Greenpeace's Naughty Little Boy chart with a score of 1.8 out of 10, although none of them are particularly good. Microsoft scored 3.3 and Sony 4.9. Tut tut.

Quick, get Captain Planet on the blower.
